A lot of cars have them as far as I know, seems more like filler to me as well. I don't think its anything revolutionary.OK, what's the deal with frameless doors? Mercedes is making this a sales point in their sales brochure. Why? What am I missing? Are they just looking for extra filler in their brochure? I don't get it.
I would imagine a framed door (where the window is entirely encased in a metal frame on the door) is stronger and better for weather proofness. I think it would form a tighter seal and seal the window glass better than a framless design.
Maybe I'm over thinking this. Does Mercedes usually put these frameless designs in their cars? I know lots of American cars in the 60's and 70's had framless designs, but that's a car era I wouldn't exactly look towards for quality/design cues. Any thoughts?
